From 3e8fba4cd41a3b324dffe921f9cd311e41f77a22 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 9 Jul 2020 18:39:31 -0600 Subject: [PATCH] binman: Add support for calling mkimage As a first step to integrating mkimage into binman, add a new entry type that feeds data into mkimage for processing and incorporates that output into the image.
